ROAD-SCRAPER.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed February 26, 1908. Serial No. 417,857.

To all whom it may concern:

Be it known that I, CYRUS H. CASNER, a citizen of the United States,residing at Hepburnville, in the county of Lycoming and State ofPennsylvania, have invented a new and useful Road-Scraper, of which thefollowing is a specification.

My invention relates to road scrapers having a forward blade forremoving a portion of the road surface and a rear blade for leveling.

The invention also provides a rake for removing stones, etc., and in animproved construction this rake is arranged adjacent to the forwardblade and both are made adjustable so that either or both can be put inoperative or inoperative position and also adjusted so as to producedifferent results when in operative position. The rear blade may also bethrown in or out of position and adjusted in a similar manner.

The invention further provides a new draft appliance by which the angleof the blades to the direction of movement may be regulated.

In the drawing: Figure l is a plan of a scraper embodying the invention.Fig. 2 is a detail view, partly in section, of the chain and boltconnection. Fig. 2 is a detail plan view of the means for connecting thechain with the pole. Fig. 3 is a side view, the draft rigging beingomitted. Fig. 4 is a front view with the pole and draft chain omitted.Fig. 5 is a detail view showing various parts disconnected. Fig. 6 is asectional view through the front bar and one of the sockets showing theadjustment devices for the rake and scraper blades.

Reference numeral 1 designates the front bar and 2 the rear bar whichmay be formed of angle iron presenting fiat faces 3 to the ground. Thesefaces slide over the ground when the corresponding blades are ininoperative position and aid in leveling the road surface. The front barcarries two lugs 4 each of which is provided with two slots 5. The frontscraper 6 rests against the front face of bar 1 and has arms 7projecting upwardly through two of the slots 5. In front of the scraperblade 6 is mounted the rake 8 which has similar arms extending throughthe other slots. The arms 7 and 9 of the blade and rake are providedwith holes 10, and each of the lugs 4 is provided with a hole throughwhich cotter pins 11 are inserted. By this means the blade 'toaccommodate the bar and blade.

and rake may be adjusted in height and placed in operative andinoperative position, as desired. The lower parts of the blade and rakemay be further guided and supported by studs 12. These are secured tothe rake and pass through slots in blade 6 and in the bar 1. The studsare grooved This construction permits the blade and the rake to be movedindependently in relation to the bar and at the same time spaces theblade and the rake apart.

The rear bar 2 is provided with sockets 13, each of which has a singleslot. The rear blade 14: rests against the front face of the rear barand has arms 15 extending through the slots in sockets 13. Arms 15 areperforated as has been described with reference to the arms 7 and 9, andthe rear blade is held in adjusted position in a similar way by cotterpins 16.

The lower edge of front blade 6 is preferably curved forward, as shown,to form a suitable cutting edge to remove a portion of the road surface.then the implement is used to out down the road, the rake is elevatedand blade 6 is dropped below bar 1 a distance suitable for the work inhand. The rear blade 141 is not intended as a cutter but serves to levelthe surface and fill inequalities. It may be adjusted to any suitableheight. Either the front or the rear blade may be made totallyinoperative by raising it to the level of face 3 of the correspondingbar. This is frequently done when one of the blades is to be used byitself. The rake is used for removing sticks and stones without cuttingdown the road surface and for this purpose scraper blade 6 is elevatedand the rake 8 dropped as shown in Fig. 6.

It is important to provide means for drawing the implement with theblades obliquely disposed to the direction of move ment so as to throwmaterial to one side of the road. This means will now be described: Aperforated rail 17 is secured to the front bar by eyes 18. To any one ofthe perforations in this bar the pole 19 is secured by a bolt and nut.The pole is provided with a slider 20. A chain 23 is connected at eachend to one end of the front bar and is connected atan intermediate pointof its len 'th to the slider by bolt 22. The slider is a so providedwith means for attaching a swingle-tree or other draft appliance. Tofacilitate connection of the chain with the bolt,

certain of the links 24 may be made round. As shown in Fig. 1 the poleis connected with rail 17 and the chain in such a way as to give acertain angle of pull to the implement. This angle may be varied asdesired by changing the connection of the pole with the rail and of thechain with the bolt. In

' may be independently adjusted.

2. In a scraper, the combmatlon of a bar having a flat face presented tothe road surface, lugs carried by the bar, a scraper blade having armsseated in sockets in the lugs, a rake having arms similarly seated, thearms being perforated and the pins passing through holes in the lugs andserving to hold the blade and rake in adjusted position.

3. The combination of a bar having a flat face presented to the roadsurface, lugs carried by the bar, a scraper blade having arms seated insockets in the lugs, a rake having arms similarly seated, the arms beingperforated, pins passing through holes in the lugs and serving to holdthe blade and rake in adjusted position, and guiding devicesintermediate the blade and the rake for supporting the lower portions ofthe last two.

4. In a scraper, the combination of a presented to the road surface, acutting.

blade having a forwardly curved edge, adjustably secured to the frontbar, a vertical smoothing blade adjustably secured to the rear bar, anda rake adjustably secured to the front bar adjacent to the cuttingblade;

7. In a scraper having a cutting blade and a smoothing blade, draftmechanism comprising a rail provided with a plurality of perforations, apole adapted to be secured to the rail by means of the perforations andmeans for securely holding the pole at any desiredangle to the axis ofthe implement.

8. In a scraper having a cutting blade and a smoothing blade, draftmechanism comprising a rail provided with a plurality of perforations, apole adapted to be secured to the rail by means of the perforations, achain secured at each end to the scraper, a slider carried by the pole,and means for securing the chain at an intermediate point to the slider.
